L6474 Driver Stalling at 15kHz step frequency
Posted on August 05, 2014 at 00:06Hello, We're having issues with the L6474PD driver and stalling. I'm testing it with the L6474PD evaluation board powered by 24V. Logic is at 3.3V. Motor runs fine below 15kHz, but right around that frequency it s...
L6474PD
I am working on L6474PD motor Driver.I could figure out that, if the input is between 8-48v it would internally regulate the voltage and supply to the logic circuit of L6474PD , but my question is will the L6474PD independently drive the stepper m...
L78xx datasheet formatting
Through the Characteristics chapter of L78XX DS, the page break is placed incorrectly so, that the conditions - and sometimes also the first row of the table itself - is at the preceding page. Yes, it's formally OK, but is this how ST intends to pres...
How to get Equation2 in AN5287
Hi there,I am studying the application note: AN5287. It provides lots of helpful information about SMPS calculation.But I don't understand Equation2. What is original formular for this?RegardsAlex Chen
I need the name of this sop8 IC
millenium mps 1000 drum moduleI need the name of the sop8 integrated circuit. The ST logo on it says ua gb145. The 8th leg is +12 volt input. The 7th leg is gnd. The 3rd leg is 2t1 smd push button. The 1st leg is out +12. Can you tell me what this in...
SCTL35N65G2V - Power flat 8 * 8 Package ( Bottom cooled or TOP cooled)
Power flat 8 * 8 package have exposed pad , but resistance from junction to board is high whereas junction to top thermal resistance is less . which makes the package top cooled .Can you update the thermal resistance values.
STSPIN958 Thermal shutdown does not work
Hi,We are using STSPIN958 for BLDC control, and under 33V, 2A, when external force applies to servo, and the current goes up to about 2A, the chip burns before the thermal shut down kicks in.I would also like to know the value of "Tsd" delay timing p...
STSPIN958 EN Delay
Have a quick question. What is the delay time from when the EN is pulled high to when the half bridge becomes non Hi-Z? Similar is disable delay time from when the EN is pulled low? I wasn't able to find this information in the data sheet. We will b...
STSPIN840 Motor Current sensing
Hi,Working on a project involving the STSPIN840 motor driver connected to a PIC32MK microcontroller,trying to implement current sensing for accurate motor control. The STSPIN840 has the current sensing pins SNSA, SENSEA1, and SENSEA2 for each channel...
Low Input Voltage to AEK-POW-BMS63EN
Hello, The AEK-POWBMS63EN is a Battery Management System. I am not sure if I can connect to a voltage lower than 48V, if yes, would it work optimally? What issues I might come into? Please kindly advise
